SERVICE TOWER.

To 'uihom it ma 'eoncern f I o it known that l, GEoizGnE, imam,- a H citizen of h United yivzrwest 24th. Street,

county of Angeles and State of Califor- State's, residing at n ag have invented new and useful Improveflnents Service Towers, of which the foliow ng is a specification.

My invention relates to service t e a ac wws b embodied in my co-pending application Serial No. 528,724 filed Januaryg12,,;1922,and apurpose of my present invention is the provision of a service tower having a plurality of airhose supporting fleyers which are mounted to rotate and rock independently of eachother and without the possibilityof interference so: that either or bothfhose can be manipulated to supply air to the tires of a single motor vehicle or to two irrespeotiveof its or their positions within the range of the hose.

flt is also a purpose of myinvention to provide .9 S-Brvice tower including a standard having simple and efiicient' brackets for securing pipes comprising the. standard in triangular formation. the construction of the brackets being such that anadditional pipe within the triangular arrangement can be'securely held in proper position. I Among the other purposes of my invention isthe provision of a service tower having nove'l means for rotatably supporting the levers; counterbalancing the levers so that they normally occupy upstanding positions; providing an adjustable and yieldab le bumper to eliminate, jars and shocks to the levers andtheir supporting elements; and providing adjustable. andrermovable means for normally urging the leve'rsto a predetermined position circumferentially with respect to a vertical axis.

Although I have herein shown and described only two forms of service towers embodying'my invention, it is to be understood that various changes and. modifications may be made'herein without depaitinglfrom'tlie spirit of-the invention and the spirit and w pe ofthe appended claims.

\ 'Siinilarreference characters refer to similar parts in each of; the several views.

Referring'specifically to the drawings and particularly "to Figures Land 2, my invention in itsjpfresent embodiment comprises a standard designated .generally at S and includinga plurality of pipes having their lower ends embedded in a base B formed of concrete or other suitable material. The pipes comprisingthe, standard Sv include an air pipe .15, an e ectrical conduit 16, a water pipev 1'7 'and. a.supporjting .pipe 18 through which no fliiidis. adapted to flow. ,Air under pressure is adapted to be supplied to the lower endof air pipe 15. by means of a pipe 15; aiidlairffriom the pipe 15 is adapted to besupplied to flexible air h0se.19and 20 by means of a common branchpipe 21 which is clearlyl'lshown inFig. Iasprovided with a nipple 2;2 ,at;s point. intermediateits ds which is connected to the upper end of pipe CALIFORNi-LA; A CORPORATION or CALifor securingthe p p in Proper by means of a union 23. An extension 24 is formed on the pipe 21 adjacent to the nipple 22 and a union 25 connects this extension with the upper end of the pipe 18. It is to be understood that the extension is solid and that the pipe 18 is connected thereto merely for the purpose of providing additional supporting means for the branch pipe The pipes 15, 17, and 18 are arranged in triangular formation as clearly shown in Fig. 4, and the electrical conduit 16 is disposed centrally of the triangle formed by the pipes 15, 17, and 18. These latter pipes are rigidly secured in triangular formation by means of brackets K arranged at suitable intervals along the length of the pipes as shown in Fig. 1. As shown in Fig. 4, each bracket K includes three clamping plates 26 each having oppositely curved extremities 27 and a curved medial portion 28 connected to the curved extremities by tapered portions 29. Bolts 30 orv other suitable fastening members are extended through the tapered portions 29 of any two. adjacent plates 26 for securing the latter in clamping relation with respect to the pipes'and conduit. As illustrated in Fig. 4, the curved extremities 27 of adjacent plates embrace the pipes 15, 17, and .18, while the medial portions 28 of all of the plates engage the conduit 16. .lVith. this arrangement it will be seen that the plates of the bracketsserve to rigidly secure the pipes in triangular formation, and the conduit centrally within the standard.

Referring again to Fig. 1, it will be seen that the distributing pipe 21 is provided at its opposite ends wlthvalved extensions 31 to which the hose 19 and 20 are connected. These hose 19 and 20 are adapted to be supported by means of levers L and L, respectively, mounted to rotate in .a horizontal plane and to oscillate in a vertical plane. As the construction ofthe levers and the mountings therefore are the same, a description of one will suflice forboth. As shown in Fig. 2 each lever L or L comprises a pair of spaced pipes 32 flattened at their lower ends for rigidconnection to a pair of arms 33 which latter in turn are mounted for rocking movement upon a bolt or shaft 34 which as clearly shownin Fig. 6 is embraced by a bearing sleeve 35 threadedly engaging the upper end of a tubular member 37 rotatably fittedon an upright 38 formed of cold rolled steel. The upright 38 is Welded or otherwise secured at its lower end by a branch pipe 21 asclearly shown in Fig. 7 while the upperend is provided with a pocket upon which is mounted a ball bearing 39 arranged to have rolling contact with the bearing sleeve 35.. V

By this arrangement, it will be seen that the tubular .member. 37 is antifrictionally supported for rotational movement upon the upright 38 so as to allow of the arms 33 and consequently the pipes 32 to rotate about the upright as a center. The ball bearing 39 also serves to rotatably support the bearing sleeve 35 and to thus permit of the rockin of the arms 33 upon the upright.

The liose 19 or 20 is connected to the lever L or L between the pipes 32 and, in the present instance by means of a collar 40 secured between the pipes 32 as shown in Flg. 1, and a movable bracket 41 rotatably mounted at the upper ends of the pipes 32 in the manner clearly shown in Figs. 11 and 12. As here shown, the bracket 41 includes semicircular members 42 which loosely receive a spring sleeve 43 surrounding the hose 19 or 20. The members 42 are provided with flanges 44 through which bolts 45 extend for securing the members in circular formation.

The members 42 are provided with stub shafts 46 which are journaled in extensions .47 and secured therein by cotter pins 48. The extensions 47 are fitted in and riveted or otherwise secured to the upper ends of the pipes 32 so that the bracket 41 is mounted for rotational movement between the pipes. This arrangement obviously provides means for movably supporting the hose 19 so as to allow unrestricted movement thereof during the manipulation of the hose and lever. By supporting the hose between the pipes 32 through the medium of the collar 40 and the bracket 41 it will be manifest that the hose is held out of contact with the pipes 32 so that excessive wear as a result of engaging therpipes will be eliminated.

. The lower ends of the arms 33 carry weights 49 adjustably supported upon the arms in the manner clearly shown in Fig. 6. These weights serve to normally urge the lever to an upstanding position as clearly shown in Fig. 1 so that irrespective of the position of the lever when the hose 19 or 20 is released, such lever will return to the upstanding position. To provide a yieldablc abutment or bumper for the lever L or L as it returns to the normal position I provide the device illustrated in Figs. 7 and 9. This device in the present instance com.- prises a bar 50 formed with openings to slidably receive bolts or rods 51 secured at one end to the arms 33 and provided at the other end with heads 52. Coiled expansible springs 53 are interposed between the heads 52 and the arms 33 so as to normally urge the bar 50 in the direction of the arms 33. The bar 50 carries a strip 54 of rubber or other suitable material which is adapted to contact with the tubular member 37 when the lever L or L is in normal position. The heads 52 are adjustable to vary the tension of the springs 53 so that the yielding action of the device can be regulated accordingly.

Referring now to Figs. 1 and 7 means is shown for normally urgingthe member 37 to a predetermined position circumfereni'tsundeir side witha groove 56 which re ceivesthe lower and bent end so that when the block is in clamped position on the pipe, the rod will be securely held within the block and against any turning move ment. A bracket 58 is adiustably'mounted upon the tubular member 87 so as to occupy any desired vertical position. This bracket 58 is adapted to clampingly engage the rod 55 so that when the member 87 is'rotated on the upright 38, the rod 55 will be flexed cir cumferentially thus placing the rod under tension. The positioning of the rod 55 is such that the member 37 and consequently the lever L or L is urged to the position shown in Fig. 1, 'so that any movement of thelever in one direction or the other from this urged position will place the rod 55 under such tension that when the lever is released the rod will operate to return the lever to normal position. Should the lower end of the rod'55 break after prolonged use,

a renewal may be effected by merely loweri-ngtlie rod within the bracket 58 and the block 56 and then rebending'thelower end of the rod, as will be understood.

The rotational movement of the member 37 upon the upright 38 is limited in both directions by means of a projection 59 formed on the lower end of the member 37 and arranged to engage the block 56 on either side of the latter depending upon the direction in which the member 37 is rotated. It will be clear that by this arrangement, the rotational movementof the lever L or L about the upright 38'is necessarily limited, and the arrangement of'the stop 59 is such as to prevent possible interference of the leverL with the lever L.

The hose 19 and 20 when not in use are adapted to be placed within the hooked ends 60 of a bar 61 suitably supported upon the standard S in the manner shown in Fig. 1. The water pipe 17, as shown in Fig. 2 is provided with a spigot 62 to which a hose 63 is connected. This hose when not in use is supported upon a bracket 64.

The electric conduit. 16 is provided at its upper end as shown in Fig. 2 with a substantially L-shaped extension 65, with its free end disposed at one side of the standard and provided with a lamp 66 and a shade 67. By supporting the lamp 66in this manner it will be clear that when the lamp is illuminated sufiicient light will be provided to allow the use of the service tower at night.

' As shown in Fig.'-3, the branch pipe 21 has secured thereto by means of brackets 68,

guard members 69 which serve to prevent the entanglement of the hose 19 and 20'with' any part of the service tower.

here shown another "formof service tower embodying my invention which is similar in constructionto the first service tower described in that the standard S includes an air pipe 70, a water pipe 71 and a supporting pipe '72 secured intriangular formation by means of"bracket.s K. A conduit '72 is arranged centrally'of the triangle and secured to the other pipes by the brackets. An upper end ofthe conduit 7 2 is connected to a T 73, and extending upwardly from the T is a solid bar 74 of cold rolled steel upon which "is rotatably mounted member 75. Theinembersil and 7 5'316 the equivalent of the members 37 and 38 and an arm L is associated with the member 75 to allow of rocking movement thereof and to rotate with the member upon the solid member 74:. Rotational movement of the member 75 is limited in either direction by means of stops 76 which, as clearly shown in Fig. 15 are adapted toengage a stop finger 77 pivoted at '78 and normally urged to a definite position by'means of springs 79. The finger "77 and the springs 79 are mounted on a yoke 80 I secured to the upper'ends of certain of the pipes as shown in F ig. 14. The branch conduit 81 extends from the T 73 and connects with a junction box 82 from which latter extend light supporting conduits 83.

The valved extension 84 is connected to "the upper end of the air pipe 70 and to a flexible air hose 85 secured to the lever L in the same manner as that described in connection with the hose l9 and 20. A faucet 87 is connected to the water pipe 72 and to a hose 88 normally supported upon a bracket 89. 7
